AUXILIARY RADIATOR FOR AUTOMOBILES;

Z'o'aZZ whomit may concern};

Be it known that I, WLLIJAM: NASH, a

citizen of the United States, residing at the city and county of Denver and State of 'Colorado, have invented certain new and useful Improvements inAuxiliary Radiators for Automobiles; and I do declare the following to be a full, clear, andexact de-- scription of the invention, such as will en- I marked thereon, which form a part of this specification.

This invention relates to radiators for automobiles, especially where they are used c for heavy work, such as tractors.

The object is to obtain more rapid cooling, and is attained by the use of an auxiliary radiator.

The invention comprises. a tank, constituting an auxiliary radiator, mounted above the engine and having connections with the water jacket and original radiator so arranged that the water passes directly from the water jacket into the tank and from the tank into the original radiator whence it is conducted back to the water jacket.

In the drawings forming a part ofthis specification,

Figure 1 is a View taken generally on the line 1-1, of Fig. 2, showing the invention in vertical section and the other parts of the power plant in side elevation.

Fig. 2 is a front elevation as indicated by the line 22 of Fig. 1..

Fig. 3 is an enlarged detail of the connection used to direct the water from the jacket to the tank and from the tank to the original radiator.

Fig. 4 shows a detail of the coupling.

The original motor 3, with its water jacket 4, and radiator 5 are used. The hood is removed and a tank or auxiliary radiator 7 is mounted on the seats 6 formerly occupied by the hood. The tank may be maintained in place by standards 11 secured thereto andv held at their lower ends by the usual means for holding down the hood, or rods may be passed over the tank at each end and secured at their lower ends in the same way as the standards.

The tank 7 by means of the pipes 8 and Y 9 has connection with the jacket l and ra- Specification of Letters Patent. Patented Sept. 21, 1920.-

diator fthroughthe medium of a coupling similar to the. ordinary coupling at this point except that it has a partition 13 forming chambers 14 and 15 and is providedwith openings in its side walls, one communicating with each'of the chambers 14 and 15to receive the pipes 8 and 9 as indicated at 16 17 respectively. The. upper'end of the pipe 8aextends to a point near the top of the tank 7 as indicated at 18 while the pipe 9 merelyenters the bottom of the tank. A filling cap 19 is provided on the tank.

, When the engine isrunning the, heated water passes from the jacket into the chamber 14: of the couplinglOandis directed by the partition 13 through the pipe 8 into the cooling tank 7 where it is discharged at point 18, the top of the pipe at this point being approximately even with the water level or slightly above it but not so high that the efiect of the heat on the water in the jacket will not cause it to overflow. In this way the hottest water is being continually discharged on the surface of the 10 locatedbetween the jacket 4: and the usual y, flexible connection 12. The coupling 10 is water at one end of the tank 7. As the I water cools, it sinks to the bottom of the tank and the coolest water isdrawn there-, from at the other end, passing through the pipe 9 to the radiator 5 where it is further cooled and then passed back to the water jacket. Y

The invention is designed mainly for use where themachine'is in the form of a trac tor and the engine heats up rapidly. The tankofi'ers a large cooling space and thereby constitutes a valuable auxiliary radiator.

In actual use this structure has furnished ample cooling means where the automobile was used as a tractor in connection with heavy farm work, under which the ordinary The hood being removed and the first to the tank, It seems that back pres-c' water to pass directly to the automobile radiator, while the bulk of the water passes ing a water jacket, of an auxiliary radiator comprising a tank, acoupling connected with the upper part of the water jacket and connected'with the automobile radiator, said coupling having a partition'therein, forming a chamber on each side of said partition, a pipe connection between each of said chambers and the tank, one chamber being in communication with the water acket and the other in communication with the automobile radiator, said partition having a small opening therethrough.

2. The combination with the engine, water jacket and radiator of an automobile, of an auxiliary radiator comprising a tank, a coupling betweenthe water jacket and'the automobile r'adiator,-said coupling having two separated chambers, each chamber having separate communication with the tank at separated points in the tank.

3. A coupling for use with an auxiliary cooling system for automobiles, said coupling having a partition therein forming two chambers, an opening for each chamber in the side of the coupling,an opening in each end of the coupling, and said partition having a small opening therethrough.

a. The combination withthe 'engine'and radiator of an automobile, the engine having a Water jacket, of an auxiliary radiator comprising a tank; a coupling connected with the upper part of the water jacket and connected with the automobile radiator, said coupling having a partition therein, forming a chamber on each side of said partition, a pipe connection between each of said chambers and'thc tank, one chamber being in communication with the water jacket and the otherin communication, with the automobile radiator.
